The protesters were still camped in front of the Cabinet office Wednesday the day after one man set himself on fire, the Yemen Times reported Thursday.
Revolutionaries went on a hunger strike following the self-immolation of Muneef al-Zubairi. They criticized Finance Minister Sakhr a-Wajih for his slow response to the protesters' demands.
Al-Zubairi is being treated in a hospital for his burns.
The protesters also accuse al-Wajih of giving money intended for people injured during the revolution to the Wafa Foundation for Caring the Martyrs' Families and Injured.
Shawai al-Maimoni, the head of the foundation, denied his organization has received money from the government, saying Wafa had only provided a list of the families of those killed and seriously wounded during the conflict.
Al-Maimoni was critical of a special government committee recently formed to follow up on the injured, saying the committee hadn't made effective steps toward treatment.
Abdulla al-Majidi, head of the Revolutionary Wounded Organization, said the government had recently sent some of the wounded abroad for treatment but charged they were "extremely selective" about who was sent.
